Version 8.1.1.0 7.6.1.0 7.5.1.0 7.4.1.0 6.1.1.0 Description Introduced on the E-Series ExaScale. Introduced on the S-Series. Introduced on the C-Series. Added the monitor option. Introduced on the E-Series. Usage Information When you use the log option, the CP processor logs detail the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packet details. By default, 10 ACL logs are generated if you do not specify the threshold explicitly. The default frequency at which ACL logs are generated is five minutes. By default, flow-based monitoring is not enabled. Use the monitor option only when you are using flow-based monitoring. For more information, refer to the Port Monitoring chapter of the C9000 Series Configuration Guide. NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. Related Commands deny - configures a filter to drop packets. permit - configures a filter to forward packets. IP Prefix List Commands When you create an access-list without any rule and then apply it to an interface, the ACL behavior reflects implicit permit. To configure or enable IP prefix lists, use these commands. clear ip prefix-list Reset the number of times traffic meets the conditions ("hit" counters) of the configured prefix lists. C9000 Series Syntax Parameters clear ip prefix-list [prefix-name] prefix-name (OPTIONAL) Enter the name of the configured prefix list to clear only counters for that prefix list, up to 140 characters long. 328 Access Control Lists (ACL)
